ASH-SIFTER FOR FURNACES.

Specification of Letters Patent.

Patented Mar. 31, 1914.

To all whom it may concern:

Be it known that I, EDGAR O. LOEBE-R, a

citizen of the United States, residing at East Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Ash-Sifters for Furnaces, of which the following is a specification. My invention relates to improvements in ash sifters for hot air furnaces, the primary object being to provide an improved ash sifter which may be readily inserted within or withdrawn from the ash pit portion of any ordinary hot air furnace, and which when inserted through the usual ash door and properly positioned within the ash pit is adapted to receive the ashes, cinders, charcoal, and partially burnt and unburnt coals, as such material falls or escapes from the grate portion of the furnace above.

A further object is to provide an improved ash sifter having its parts so arranged that they maybe collapsed or contracted so that they may be inserted through the usual ash door opening, and after being placed in the ash pit portion may be expanded or set up for use, the improved sifter being movably mounted within the ash pit so that it may be agitated from the ash door.

opening to sift the ashes and at the same time form a receptacle to accumulate the refuse matter, including unburnt coals, and the like, so that the sifter and receptacle may be removed through the ash door and the partially consumed fuel, and the like, returned to the furnace through the fuel doors.

A still further object is to provide a receptacle and sifter having resilient runners or supporting means whereby the receptacle and sifter is adapted to move downwardly from the grates by the weight of the accumulations, and to move upwardly toward the grates as relieved of the superposed load by the sifting of the material deposited therein.

With the above-mentioned and other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in some of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings forming a part I mal position beneath the of this specification, Figure 1, is a perspective view of the improved ash sifter as it appears in the ash pit portion of an ordinary furnace, the walls of the latter being broken away for the purpose of clearer illustration of the parts. Fig. 9., an enlarged central vertical section of the base or ash pit portion of a furnace showing a modified form of ash sifter. Fig. 3, a perspective view of a portion of one of the wings of the improved ash sifter and receptacle. Fig. 4, a perspective view of a further modification in which the wings are hingedly connected to the ash receptacle and sifter.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

The improved ash sifter comprises a combined ash receptacle and sifter 1, preferably of wire Or other suitable foraminous material, said receptacle and sifter 1, being of suitable dimensions adapting it to be inserted through or drawn from the usual ash door neck 2, and ash door opening 3, of an ordinary furnace,

The improved ash receptacle and sifter 1, is adapted to be movably supported within the ash pit portion 4, of the furnace in some suitable and convenient manner, preferably by means of resilient supporting runner members 5, as shown in Figs. 1 and 4;, of the drawings, so that the receptacle and sifter 1, may be reciprocated or agitated within the ash pit portion in some suitable and convenient manner, as for eX ample,by means of a handle 1*, as shown in Fig. 1, of the drawings. The supporting runners 5, are preferably formed of sufficiently resilient and flexible material relative to the superposed load that the weight of the material filling the ash receptacle will cause the latter to be depressed and permit the accumulating material to be depressed from the grate bars when the receptacle is full or overloaded, and at the same time, when the ash receptacle and sifter is reciprocated or agitated relieving the receptacle of the superposed load will be elevated to regain or partially regain its ordinary or norgrate bars.

As a means for catchlng and deflecting material falling from the sides of the grate bars at the sides of the receptacle and sifter 1, sitter wings or deflector members 6, are provided, said wings being adapted to be either supported and mounted independently of the receptacle and sitter 1, as shown in Figs. 1 and 2, or if desired, hingedly connected to the sides of the receptacle and sitter, as shown in Fig. 4 of the drawings. In the latter instance, the wing members are .secured by means of hinge straps 7, and are adapted to be supported in their open inbers 9, being provided at their ends with supporting legs 9. The base portions of the sitter wings 6, may be adjustably supported upon the supporting members 9, through the medium of supporting bolts or pins 10, the latter being adapted to be adjusted and supported in bolt or pin receiving openings 10, as shown in Fig. 1, of the drawings, or if desired, the cross members or straps 9, may be offset to form shoulders 9 as shown in Fig. 2, of the drawings. If desired, the ash receptacle or sitter 1, may be removably mounted beneath and suspended from the cross or supporting members 9, by means of depending chains 11, carried by the supporting members 9, the lower ends of said chains 11, being provided with cross bars 12, as shown most clearly in Fig. 2, of the drawings. Or if desired, the supporting members 9, may be dispensed with by hingedly connecting the sitter wings 6, to the upper edges of the sides of the receptacle and sitter 1, as shown in Fig. 4, of the drawings, and in which instance the wings 6, are supported directly from the receptacle and sitter and are agitated with the latter during the sitting operation.

From the foregoing description, taken in connection with the accompanying draw ings, the operation and advantages of my invention will be readily understood.

Having thus described some of the embod- 3. In an ash sitter for furnaces, an ash receptacle and sitter, means for resiliently (and movably supporting the same within the ash pit and beneath the grate bars of a furnace, sitter wings at the sides of said ash receptacle and .sitter, and means for supporting said wings in their open or operative position.

4:. In an ash sitter for furnaces, a combined ash receptacle and sitter adapted to be inserted through the ash door opening of a furnace, and resilient supporting runners connected to said ash receptacle and sitter and adapted to movab'ly and resiliently support the latter within the ash pit portionanrl 1 beneath the grates of the furnace. v

5; An ash sitter for furnaces, comprising an ash receptacle and sitter adapted to be inserted within the ash pit ot a furnace through the ash door thereof, resilient runners adapted to support: said receptacle and sitter beneath the grate bars and to move downwardly therefrom duringthe accumulations of material within said receptacle and sitter, sitter wings at the sides of said receptacle and sitter, and means for supporting said wings in their open or opera: tive positions, all of said parts being adapted to be collapsed whereby they may be inserted through or removed from the ash door opening of the furnace.

In testimony whereofI have aflixed my signature in presence of two witnesses.
